Maximum Method Name Length

问题 Does anyone happen to know what the maximum length of a method name is in your programming language of choice? I was going to make this a C# specific question, but I think it would be nice to know across the spectrum. What are the factors involved as well: Does the language specification limit this? What does the compiler limit it to? Is it different on 32bit vs 64bit machines? 回答1: For C# I don't believe there's a specified hard limit. (Section 2.4.2 of the C# 5 spec doesn't give a limit,

Programmatically determine maximum filename length

问题 How can I determine the maximum filename length on a linux box? Preferred in PHP programming language. 回答1: You want pathconf or fpathconf, which are not exposed (yet) in PHP. (When they are, they'll probably be posix_pathconf .) You may also shell out to getconf, a command-line utility interface to the same functionality. Try this on your system: $ getconf NAME_MAX /tmp $ getconf PATH_MAX /tmp 回答2: there's no need to programatically determine it. it's 255 bytes. edit: you can have longer

问题 This question came up in Spring class, which has some rather long class names. Is there a limit in the language for class name lengths? 回答1: The Java Language Specification states that identifiers are unlimited in length. In practice though, the filesystem will limit the length of the resulting file name. 回答2: 65535 characters I believe. From the Java virtual machine specification: The length of field and method names, field and method descriptors, and other constant string values is limited

Maximum Possible File Name Length in Windows Kernel

谁说我不能喝 提交于 2019-12-12 11:13:00
问题 I was wondering, what is the longest possible name length allowed by the Windows kernel? E.g.: I know the kernel uses UNICODE_STRING structures to hold all object paths, and since the byte length of a wide-character string is stored inside a USHORT , that allows for a maximum path length of 2^15 - 1 characters. Is there a similar, hard restriction on a file name (rather than path)? (I don't care if NTFS or FAT32 imposes a particular restriction; I'm looking for the longest possible

Internet Explorer: FileUpload control doesn't recognize files with long file names

问题 You might think after reading this question that it is somehow unrealistic but the below situation is there in one of our production applications. One of our users reported that he is getting an error if he tries to upload files with too long names, we got to fix that by limiting file names to not exceed 255 chars including file extensions. But we faced another weird behavior that is there in Internet Explorer only. If user tries to upload a file that its length including extension is 255
